Abstract

In a fuel injection system, in order to prevent an intake air sensor to transmit those forces to a fuel control valve which are generated upon sudden thrusts of air in the engine intake tube, there is provided a valved passage which connects intake tube portions upstream and downstream of the intake air sensor and which opens in response to a predetermined pressure differential prevailing across the intake air sensor.
